推荐答案

您可以使用下面的代码，该代码需要4个文件并创建将所有文件的所有数据附加到一个文件后. you can use below code which takes 4 files and create a single file after appending all data of all files. static void Main(string[] args) { string[] Filename = new string[4] {@"F:\Test\2012_03_05_055030.txt", @"F:\Test\2012_03_05_055035.txt", @"F:\Test\2012_03_05_055040.txt", @"F:\Test\2012_03_05_055045.txt"}; string text = System.IO.File.ReadAllText(Filename[0]); int count = 1; while(count < Filename.Length) text += System.IO.File.ReadAllText(Filename[count++]); // Write the string to a file. System.IO.StreamWriter file = new System.IO.StreamWriter(@"F:\\Test\\Test.txt"); file.Write(text); file.Close(); //Delete the file count = 0; while (count < Filename.Length) File.Delete(Filename[count++]); }

将数据附加到第一个文件本身的代码.正如我先前的答案创建一个新文件一样，但是此解决方案会附加到第一个文件本身. Code which appends data to the first file itself. As my previous answer creates a new file but this solution appends to the first file itself. static void Main(string[] args) { string[] Filename = new string[4] {@"F:\Test\2012_03_05_055030.txt", @"F:\Test\2012_03_05_055035.txt", @"F:\Test\2012_03_05_055040.txt", @"F:\Test\2012_03_05_055045.txt"}; string text=""; int count = 1; while(count < Filename.Length) text += System.IO.File.ReadAllText(Filename[count++]); // Write the string to a file. System.IO.StreamWriter file = new System.IO.StreamWriter(Filename[0]); file.Write(text); file.Close(); //Delete the file count = 1; while (count < Filename.Length) File.Delete(Filename[count++]); }
